#### *3.1. Classification Accuracy Evaluation*

The accuracy assessment gave overall accuracies of 87.06~97.38% for the images of all the islands. Meanwhile, the kappa coefficient was 0.84~0.96. Images of larger islands coincide with higher accuracy, whereas images of smaller islands coincide with lower accuracy. The user and producer accuracies of the various thematic classes were over 81.3%, except for ponds (70.3%), reservoirs (72.7%), and bare lands (71.2%).
